Question

Why do federal district courts not try cases dealing with military matters, grievances against the government, or tax disputes? They cannot be expected to rule impartially on cases involving the government. Original jurisdiction for such cases belongs to the Supreme Court. Such cases are tried only in state courts, not in federal courts. Congress has created specialized courts to deal with such cases.

Answer 1

Congress has created specialized courts to deal with such cases.

military matters, grievances against the government, or tax disputes are not dealing by federal courts as there are courts specialized in such cases, this is because often those type of cases involves military law, which is entirely different from civil law, so it make sense that specific courts should deal with those types of cases.
